| Abstract: | As the Doppler flowmeters for pipe-flow measurement have poor performances at present, the measurement methods and techniques were improved. A new flowmeter product was implemented based on a high-speed digital signal processor according to the novel ultrasonic Doppler method. The new ultrasonic Doppler flowmeter has the advantages such as to decide the flow direction, to measure the low-velocity flow, good stability, high dynamic response speed and real-time performance. It has a good prospect for promotion and application. |
